While many of those won't be available until the tournament lead-up truly begins, the wider Australia U20s squad will travel to Canberra on Wednesday for a camp at the AIS, with Harry Chapman, Vaauli Faamausili, Angus Allan, Theo Strang, Alex Horan, Isaac Lucas, Tony Hunt, Will Eadie, James Ramm and Jayden Ngamanu all drafted in for that.

U20s coach Simon Cron said the preparation for Georgia would focus on the basic mental and physical skills they need to work on, after a mixed Oceania U20s tournament.

“The Australian Sevens contingent still have a final two tournaments so those players will join us in Georgia. They will all have high aerobic and anaerobic capacities which is essential during a world cup campaign," he said.

“Our performances against New Zealand, Samoa and Fiji highlighted a number of key areas we need to work on in our sessions.

"Some rugby brains, in regards to game management, is a key, as well as the execution of catch and pass skills while running so these will be high on our priority list.”

Australia takes on Wales, Samoa and England in its pool matches in Georgia.
